Q40 frequency

[under a big sky]

Hi folks

please excuse my ignorance as a Q40 newbie - a quick question- on a recent dig I changed frequency to avoid interference from other detectors and allso from nearby overhead power cables.

When I don't have any interference is there a 'best' frequency to be set to for sensitivity & depth?
ie what is the default frequency out of the ones available on the machine?

Many thanks.

The Q40 is a 13khz machine, the amount of deviation in the frequency offset is absolutely minimal when you do a frequency shift so it doesn't really matter, it's only there to "feather out" interference.
